To speed germination the seeds need to be scraped with a file or rub them between two sheets of sand paper, a process called scarifying, and then soak them overnight in tepid water.1
The seeds are ready to harvest when they turn black. Any seeds that remain gray should be discarded. For use in jewelry the seeds should be dried in the sun for a day or two prior to use.1
These estimates for how long Job's tears takes to sprout, grow and harvest are from real observations from real gardeners, right around the world.
